Diagnosis of atypical choroidal malignant melanoma using N-isopropyl-p-(123I)-iodoamphetamine single photon emission computed tomography.

摘要

A choroidal malignant melanoma usually presents as a sessile or dome-shaped pigmented mass. The simultaneous presence of more than one primary uveal malignant melanoma is rare. A positive correlation between increased N-isopropyl-p-[~(123)I]-iodoamphetamine (~(123)I-IMP) accumulation and melanin production has been demonstrated, and the positive accumulation of ~(123)I-IMP is diagnostic for a primary ocular melanoma. Theoretically, secondary
